Hi I am looking to convert a crossflow to run on bike carbs, has anyone done this and where did you get the inlet manifold, what did it cost, which carbs did you use and why also finally have you any pics available

Im installing bike throttle bodys on my crossflow, I fabricated a steel manifold.Seee my photo archive for more pics.

Nice !! what fuel pump are you using/going to use ??

Jason
Also, what thickness tubing have you used ??

Im planning to use a Bosch external type pump from a Vx Carlton, Just need to decide whether to feed from a seperate swirl pot or build one into the existing fuel tank.
I used 1.5mm wall exhaust tubing and 10mm plate .

Hi if it,s any help have a look in my photos archives im putting zx9r carbs on a 2l pinto Jacko

stunning answer !! , will add it to me list of parts to get !!
Cheers

Jason

oh, also am using R6 carbs hopefuly, but might have the option of ZX9 ones

Jason

Thanks for that, impressive stuff, I'm thinking of R6 carbs...38mm but does anyone know if they have a TPS as standard??

I'll have a look at my R6 ones tomorrow when I go to the garage , and let you know.
I'll measure them as well as I thought they were slightly smaller than 38mm

I've been thinking of putting some bike carbs or possibly throttle bodies on my crossflow ,I have a weber manifold that I was thinking of using. Looking at weber carb set ups it appears that 34mm choke would be the ones to use . I suspect that 34mm bike carbs or TBs would be the size to use? Too big would cause problems because of low air speed without any gain in top end

yep that sounds right to me as well, I measured the carbs i have and the choke size is 36.4mm, so maybe a tadge over size but, I'm sure i can live with it, maybe I'll just have to rebore the block to make it suit the carbs !!

Jason

If going the carb route, choke size is an issue. With throttle bodies less so, as the speed of the fuel is more down to the pressure at the injectors.

(also thinking of an injected crossflow)

If I am right bike CV carbs have variable venturi (in form of vacuum operated slides). So just pick a set that can deliver the amount of fuel your engine needs (most common are R1, Blackbird and other big bike carbs). My blackbird carbs on my 2.0L zetec seem to deliver the goods. I chose them because they had a throttle pot attached I could match up to my existing 3D ignition system.

Call Bogg Bros 01944 738234

they know what they are doing in this field.

Forgot to add earlier, the carbs I hope to use have a 3 pin plug bit at one end which lines up with the butterflies, I'm guessing this would be for a throttle position sensor

i managed to get my Mum's renault 19 running on bike carbs. The plan is to fit them to a nova but i don't have an engine yet and i'm impatient : ). Would be challenging to set them up without a rolling road though.

She did when she started it hahaha. Only messing car was scrap yard fodder anyway. Still have no nova, cos i got an mk2 xr2 instead! I'm thinking 2 liter zvh conversion on bike carbs. No i am not a boy racer!
